Triticum Agricolam Posted June 29, 2016 Report Share Posted June 29, 2016 if the port extends down the back wall of the box it would be 2 common walls correct? Nope, still a 1 common wall port. The way to tell is to look at the inside mouth of the port and then count how many walls it has in common with the rest of the box at that point. Bends and turns in the port don't matter.

ShadeTreeMechanic Posted June 29, 2016 Report Share Posted June 29, 2016 If the port is 3 inches wide and it is 3 inches from the back wall then the port will claim part of the back wall. One half port width down the wall past the port will belong to the port. Ideally you would want the port opening to be at least 2x the width away from the back wall. Use this to your advantage and make the port wider and / or taller and let it use the back wall. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
xpoppadaddyx Posted June 30, 2016 Author Report Share Posted June 30, 2016 Ok keyed in different dims and messed around with the port. Looks like everything should be in tact for this enclosure. Wadda you think? Also, I would like to see how this does in WinIsd and I have the program, however it doesn't have my driver in the database. Need a quick course on how to plot here is the model. tried to get the dims shown as much as I could 2002 Chevy Trailblazer (Build) 2013 Nissan Altima (Build) Poppa's YouTube Channel Poppa's FB Page Poppa's Instagram Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted June 30, 2016 Report Share Posted June 30, 2016 Everything looks good, except your net volume is pretty high. Rockford recommends 1.5 cu ft per sub and you are almost 50% over that. That may not work out well.

xpoppadaddyx Posted July 1, 2016 Author Report Share Posted July 1, 2016 Okay I see. I redid it so hopefully this will work. I'm going to port on the front and place the subs on top. 2002 Chevy Trailblazer (Build) 2013 Nissan Altima (Build) Poppa's YouTube Channel Poppa's FB Page Poppa's Instagram Link to comment Share on other sites More sharing options...
xpoppadaddyx Posted July 8, 2016 Author Report Share Posted July 8, 2016 So here's what I'll be building within the next couple of weeks for my build log which is on hold because I let my in-law borrow PoppaBlaze. Very basic, but will do the job and I might add a few features. I'll just have to see. 2002 Chevy Trailblazer (Build) 2013 Nissan Altima (Build) Poppa's YouTube Channel Poppa's FB Page Poppa's Instagram Link to comment Share on other sites More sharing options...
